Five Adam Curtis films you must see

Probably because it's the latest and the freshest in my mind, but this series of films on the downfall of the USSR and the failure of democracy in Russia was truly incredible. Forgoing the usual narration by Curtis himself and the lack of a soundtrack, the (incredible) stock footage really comes to the fore, which made the whole series an almost vicarious experience. I certainly felt the pain, anguish and loss of hope that the Russian people felt, woefully ignored by the West, the price of which we are paying now.
